Using AutoMap 3D to create a shapefile

Using RAM 148

Daryl Hines

The Source CAD File •It is your decision whether to make any changes to the layer structure in your current CAD template.

•The object is to select and attribute only a few elements from your CAD drawing and export them as a shapefile.

•If placing these features on different layers, renaming layers, or establishing any other standards that facilitate an eventual export, copy, or save down into this separate DWG will speed or enhance this process, then you might make these types of modifications to your CAD workflow.

•Your challenge is to make this process as seamless and easy as possible.

•How you, as CAD operators, get to this point is up to you, as only you know what will work best within the CAD framework and software you operate with.

•Today is a good time to share your expertise and experience with others.

Considerations before beginning

• Export to Kentucky Single Zone Coordinate System• Contain only the following:

• Proposed Boundary• Current Approved Boundary• Fills• Permanent Impoundments• Haul Roads• Bonding Increment Boundaries (if applicable)

• All export features must be closed polygon elements.• For haul roads, the polygon area would be the right of way

edges but if the roads are polylines these could be buffered into polygons.

• Need to exclude non-permitted areas (create donuts).• Create or use template provided for object data table?

Assign Coordinate System

Because if you will be exporting to Ky Single Zone (ft) the software needs to know your current coordinate system

ADESETCRDSYS

Assign Coordinate System

ADESETCRDSYS

Assign your Coordinate System (for this drawing KY83F)

ADESETCRDSYS

Assign your Coordinate System to your drawing(remember this does not transform the drawing)

ADESETCRDSYS

next

The exported features need to be closed polygons

Closing features

The exported features need to be closed polygons….

In PROPERTIES are polylines set to “closed”?

next

If there are areas within the permit boundary that are not permitted then they need to be excluded

Creating polygon with islands, holes, or discontinuous polygons

Use PROXYGRAPHICS, GROUP, and MAPPOLYLINETOPOLYGON commands

1st Set the PROXYGRAPHICS system variable to 0 (does not save image with the drawing; a bounding box is displayed instead)

Creating polygon with islands, holes, or discontinuous polygons

Select inner and outer polygons to group

Use Group command Name Group Select polygons

Creating polygon with islands, holes, or discontinuous polygons

Select the group and then; MAPPOLYLINETOPOLYGON

Looking back and moving along

Assign current coordinate system (ADESETCRDSYS) The exported features need to be closed polygons

(PROPERTIES) If there are areas within the permit boundary that are not

permitted then they need to be excluded (PROXYGRAPHICS, GROUP, and MAPPOLYLINETOPOLYGON)

Attributes need to be assigned. Use template or create object data table?

We will look at creating a new one first.

ADEDEFDATA

So, we need to end up with a table that looks like this within GIS software..

Define Object Data

Command ADEDEFDATA

ADEDEFDATA

Table name is up to you

ADEDEFDATA Table name is up to you

ADEATTACHDATA Now that we have the object table’s

fields it’s time to select the objects and attach the table

ADEEDITDATA At least two ways to

edit object data, to add permit information.

ADEEDITDATA Select all of the objects that will be

attributed

ADEDITDATA

In the value box type in the appropriate information for each field that applies.

Second method is to use the PROPERTIES command.Select object and type in values.This is a good way to attribute many objects at one time!

Add object data.Hit the enter key after each update

RAM 148-

MAPEXPORT

Now that we have attributed the objects it’s time to export them out as a shapefile..

1st name it correctly; example (8605607_NW or

8605607_AM_3) and .shp extension

MAPEXPORT

2st choose polygon

MAPEXPORT

3rd Coordinate conversion if necessary. Type in KY83F if not already in KY83F.

4th Treat closed polylines as polygons? May be useful to your business needs.

NAD 83 Kentucky Single Zone US Feet

Select objects to export

Several options; choose the one that is best for you.

Check your work..

Use free ArcGIS Explorer to check work? http://www.esri.com/software/arcgis/

ArcGIS Explorer (free)

Add your shapefiledata here

Right mouse clickfor “Properties”

Mouse click on mapto open table

Using a template with the object table Open map template Use INSERT command to add your

drawing Use “locate using Geographic Data”

option

Attach Object Data (supplied with the template) Use

ADEATTACHDATA command

Select objects to attach

Now you are ready to edit object data using ADEEDITDATA back in slide 24…
